Reliable battery so far
I have been using since I purchased & can only say that it is working as hoped. I plan to purchase another for backup soon.

Better for the price.
Fits my Bosch tools and charger. Better than I thought it would be.

A perfect replacement at a fraction of the cost
These batteries are a 1for1 replacement of Bosch batteries. Seem a bit heavier but work fine. Given lithium battery reputation for causing fires, I can’t stop wondering what’s the real internal difference with Bosch so I’m being cautious till I get real experience with them.

Looks like its the original battery, just no Bosch on the side!
Why did you pick this product vs others?: So far I am very impressed. Retail on the battery with 2 AH, which is their running time is $80.00 everywhere. This battery with 4 AH was $35.00 Granted it is not a Bosch battery, but it fits my tools, goes in the charger and works like my other OEM batteries. I needed a new battery and the cost for an OEM was just too much. If I have any problems with this battery I will update my post.

Did not work!
Did not work! Indicator showed full charge and my voltmeter showed a full 20V, yet it would not power up my Bosch model DDS181 18V 1/2in drill. The battery mechanical interface looked identical to my other original Bosch battery but it would not power up the LED or motor. Set back for a replacement...same story!! Note that it is recognized by and accepts a charge from my Bosch charger, but simply doesn't work with the drill (which works great with the original 2AH battery).

Hasta ahora bien
Pues no lo he usado así como en alta demanda ya que soy mas de "hobbie" con las herramientas pero no noto mucha diferencia con las ProCore de Bosch en herramientas básicas, me faltaría probar en herramientas PROFACTOR pero obvio no se van a comprar con una de 8ah
